प्रलोभयन्तीं जगृहुर्मत्वा मूढधिय: स्त्रियम् ॥ ३७ ॥
matvā mūḍha-dhiyaḥ striyam
The asuras, clouded in their understanding, took the evening twilight to be a beautiful woman showing herself in her alluring form, and they seized her.
The asuras are described here as mūḍha-dhiyaḥ, meaning that they are captivated by ignorance, just like the ass. The demons were captivated by the false, glaring beauty of this material form, and thus they embraced her.
